(1) Avoidance
OSTO® is made of waste products that would be incinerated. Low Carbon Materials prevents this waste being burnt which would immediately release harmful greenhouse gases into the atmosphere.
(2) Mineralisation
OSTO® sequesters and stores CO2 in the aggregate, and therefore locks it within the resulting concrete permanently.
(3) Reduction
OSTO® reduces the reliance on traditional carbon intensive lightweight aggregates, therefore, enables construction firms to replace carbon-intensive materials in their value chain.
Granule Size ~ 0-8mm
Particle Density ~1600kg/m3
Bulk Density ~ 750 kg/m3
Natural Moisture Content: ~ 10%
Weight x2 lighter than traditional mineral aggregates

OSTO® is a carbon-negative lightweight aggregate with broad application potential, including use in concrete mixes, screeds and resin-bound applications.
OSTO® can be used in a variety of concrete applications.
One of the most exciting uses is to create carbon neutral medium-dense concrete blockwork.
Customers should check that the product's properties are suitable for their specific application prior to use.
Depending on performance and carbon targets, a notional replacement of OSTO® within bound construction materials is likely to be in the order of 3 to 15%. However, a testing ladder substituting OSTO® for aggregate is recommended to ensure that optimum design is achieved.
Simple Switch
OSTO® can be used as a ‘like for like’ replacement for traditional lightweight aggregates that are normally used in concrete. This ‘drop-in’ solution is a game changer for a hard-to-abate sector like construction as it can greatly reduce the carbon footprint of projects in which it is used with a simple switch.
